Grilled Green Beans in Mustard Vinaigrette

1 1/2 pounds fresh green beans
7 Tbsp. olive oil
1 Tbsp. Dijon mustard
2 Tbsp. white wine vinegar
1/4 tsp. salt
1/4 tsp. pepper

•Preheat a grill to medium heat. Place either a grill pan or aluminum foil directly over the heat.
•Trim the ends off the green beans and discard, then toss the trimmed beans with about 1 tablespoonful of oil.
•Add the beans to the grill and cook about 5 minutes, turning occasionally to avoid burning. Remove from heat when just tender and set aside.
•In a large bowl, whisk together the mustard and the vinegar. Add the remaining oil slowly and continue whisking until well combined. Add the salt and pepper and whisk again.
•Add the green beans and toss until well coated. Serve warm.
